# Per-service security checklist

The bar every service (a per-service role — ADR-004) must clear **before deploy**,
especially anything reachable beyond its own host. Established by **ADR-002**
(Security baseline and strategy); referenced from `docs/runbooks/new-role.md`.
Enforced manually in review today; the planned `/security-review` skill (see
`docs/TODO.md`) will automate the check.

Treat each item as must-pass **unless** a deviation is recorded in
`docs/security/accepted-risks.md` with a rationale and a revisit trigger.

## Secrets & credentials

- [ ] All secrets live in an encrypted `vault.yml` (`vault.<service>.<key>`); none in
      plaintext files, templates, or Compose env literals
- [ ] No default or vendor-shipped credentials remain — admin passwords/tokens are
      generated and stored in vault
- [ ] Nothing secret is baked into an image or committed to git (gitleaks must pass)

## Least privilege

- [ ] Container runs as a non-root user where the image supports it
- [ ] No `privileged: true` and no host network mode unless explicitly justified
- [ ] Only the volumes/paths the service needs are mounted; read-only where possible
- [ ] Linux capabilities dropped to what's required (no blanket grants)

## Network & exposure

- [ ] Every listening port is declared in `group_vars` firewall definitions — never
      opened ad-hoc on a host
- [ ] The service is not published directly to a LAN/WAN port if it can sit behind the
      reverse proxy instead
- [ ] Anything reachable beyond the `srv` VLAN is behind the reverse proxy **with
      authentication** (and TLS)
- [ ] Inter-service reach follows least privilege — no broad `srv`→`srv` access where a
      single declared dependency suffices

## Updates & provenance

- [ ] Image/source version is pinned (tag or digest), not floating `latest` (ADR-011)
- [ ] The update path is known — how this service gets patched

## Operability (security-adjacent)

- [ ] Logs go somewhere reviewable (central aggregation when available)
- [ ] Backup/restore is covered if the service holds state

> Deviations are allowed but must be **conscious**: record them in
> `docs/security/accepted-risks.md`, don't leave them implicit.
